Samsung 840 EVO 500GB SSD Review


ATTO & AS-SSD Benchmarks

ATTO v2.47

ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5KB through 8192KB transfer sizes with the total length being 256MB.

ATTO – Intel Z77 Platform:



Benchmark Results: Very strong scores for the 840 EVO which was actually a bit surprising as we thought they would be more inline with what we saw on the original 840 drive not better than the 840 Pro drive! It definitely lives up to its specifications.

AS-SSD (1.6.4237.30508) Benchmark – Intel Z77 Platform:

We have been running the AS-SSD Benchmark app for over some time now and found that it gives a broad result set. The programmer has worked very hard on this software and continues to make updates often so if you use it, show him some love and send him a donation. There are now three tests that are found within the tool and we’ll show the results from two of them.



Benchmark Results: Again, we were a bit surprised to see the write scores fare as good as they did on this benchmark which were again better than the Pro drive. The scores are very impressive!

AS-SSD Compression Chart

Benchmark Results: Other than the anomalous dip, the performance is very steady across all manner of data compression proving that it’s data agnostic in terms of compressibility.
